Is there a function or a way to count how many pitches are present in an omn list .

Thank you

(get-count omn :length :note :sum t)

If you don't want to count all notes in a tie-chain, you could do this first.

(setf tst (omn-merge-ties (flatten-omn omn)))

(get-count tst :length :note :sum t)

Thank you
